After the introduction of new APIs last year, Microsoft has released SkyDrive SDKs for almost every major platform including Windows 8, JavaScript Web library, Android and iOS. Now the cloud service has opened its doors to more of Microsoft's own with new SDKs for .NET and of course, Windows Phone 8. To entice even more developers to its side, the team at SkyDrive also integrated with services like IFTTT (If This Then That), which lets you customize action triggers between different web services, DocuSign, an electronic signature site and SoundGecko, a text-to-audio transcription service. It'll likely take a lot of work for SkyDrive to win over fans of Dropbox and Box.net, but opening up its doors to developers is a step in the right direction.
